Strap for Equestrian 30 Diamond / Arabic

The lug width of the Longines Equestrian L6.131.0.73.2 is precisely 14mm. This measurement should be verified by placing a digital calliper between the two metal lugs protruding from the case at 12 and 6 o'clock. This is a non-standard dimension, making it essential to source straps specifically designed for this width to ensure proper visual balance and fit on the case.

The ideal strap depends on intended use and personal preference. For aesthetic coherence with the model's equestrian heritage, we recommend mahogany alligator or chocolate-brown vegetable-tanned calf leather. For active sporting use, black grained calf offers superior grip and practicality. If you prefer a versatile option, dark vegetable-tanned calf develops a natural patina that harmonises beautifully with the stainless steel case over time.

Strap replacement requires a spring bar tool and gentle lateral pressure. Position the watch on a soft surface with the caseback facing upward. Locate the small metal pins at the lug extremities and insert the spring bar tool into one of the lateral holes, applying gentle pressure to compress the internal spring. Once the pin is released, remove the old strap and insert the new one by reversing the procedure. If you lack experience, entrust the task to a qualified watchmaker.

Any strap manufactured for a 14mm lug width is compatible with the L6.131.0.73.2. Milano Straps offers a specialised collection of 14mm straps customisable in leather type, colour, and stitching details. It is critical to purchase from reputable suppliers who guarantee precision in measurements, as even a 0.5mm deviation could compromise aesthetics or create unwanted play on the case.

Leather strap longevity depends on tannage quality, intensity of use, and climate conditions. A high-grade leather strap (alligator, shell cordovan, vegetable-tanned calf) typically lasts 2-4 years with moderate daily wear. With vegetable tanning, the strap develops a desirable patina and tends to harden over time, potentially extending useful life to 5-6 years. Frequent exposure to moisture and perspiration reduces this duration. Casati Milano's 18-month warranty covers construction defects and permits maintenance interventions.
